Don't refer directly to PHP `dom` extension classes; avoid nonstandard behavior These changes ensure that DiscussionTools is independent of DOM library choice, and will not break if/when Parsoid switches to an alternate (more standards-compliant) DOM library. We run `phan` against the Dodo standards-compliant DOM library, so this ends up flagging uses of non-standard PHP extensions to the DOM. These will be suppressed for now with a "Nonstandard DOM" comment that can be grepped for, since they will eventually will need to be rewritten or worked around. Most frequent issues: * Node::nodeValue and Node::textContent and Element::getAttribute() can return null in a spec-compliant implementation. Add `?? ''` to make spec-compliant results consistent w/ what PHP returns. * DOMXPath doesn't accept anything except DOMDocument. These uses should be replaced with DOMCompat::querySelectorAll() or similar (which end up using DOMXPath under the covers for DOMDocument any way, but are implemented more efficiently in a spec-compliant implementation). * A couple of times we have code like: `while ($node->firstChild!==null) { $node = $node->firstChild; }` and phan's analysis isn't strong enough to determine that $node is still non-null after the while. This same issue should appear with DOMDocument but phan doesn't complain for some reason. One apparently legit issue: * Node::insertBefore() is once called in a funny way which leans on the fact that the second option is optional in PHP. This seems to be a workaround for an ancient PHP bug, and can probably be safely removed. Bug: T287611 Bug: T217867 Change-Id: I3c4f41c3819770f85d68157c9f690d650b7266a3
